Patented May 1, 1934 SUPPGBZT FOR OXYGEN TENTS AND OTHER ARTICLES Jay A. Heidbrink, Minneapolis, Minn. Application July 14, 1933, Serial No. 680,433

10 Claims.

My invention relates to supports for oxygen tents and other articles. One use to which my device may be applied is as a support for an oxygen tent of the nature disclosed in my prior application Serial Number 567,404, filed October 7. 1931. In administering oxygen therapy and the like to patients such as pneumonia patients, for instance, the head of the patient is enclosed in a tent supported from above and to which the oxygen or other gas is supplied from suitable apparatus. One of the objects of my invention is to provide a device by means of which the tent referred to may be supported in convenient and advantageous manner. Another object is to provide a device which may be utilized as a support for various articles and which may be easily folded so as to occupy a minimum of space and which may be readily transported.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and the novel features of my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate a practical embodiment of my invention,

Fig. 1 is a side elevational view of the device in set-up condition. Fig. 2 is a vi w in vertical section on the line 2-2 of Fig. 1 taken on an enlarged scale. Fig. 3 is a view in vertical section on the line 3-3 of Fig. 1 taken on an enlarged scale. Fig. 4 is a side elevational view partly in section showing a supporting bar held in upwardly-inclined position. Fig. 5 is a fragmentary view in side elevation showing a device partly folded. Fig. 6 is a view in side elevation showing the device completely folded.

As shown in Fig. 1 of the drawings, a customary or suitable base it is mounted on caster wheels 12 and has a standard 14 extending up centrally 0 therefrom. The standard 14 preferably consists of a pipe section and the upper end thereof is externally threaded to receive a socket 16 formed on the lower end of a short flat bar 18. The bar 18 is straddled by the lower end of an arm 20 which is pivotally attached thereto by a pivot pin 22. This lower portion of the arm 20 is partially cut away so that the arm when in alinement with the bar 18 can swing in one direction only, as will be understood from Fig. 4. The

arm 20 carries a second arm 24 extending therefrom at right angles. The arm 24 is hollow and the forward portion thereof is cut away on the upper side as shown in Fig. 4. The two lateral sides of the hollow arm 24 are provided with similar bayonet slots 26, the short angular portions of which are at the rear or adjacent the arm 20, as best shown in Fig. 6. The rear end of a supporting bar 28 is slidably mounted in the arm 24. This end of the bar 28 is provided with a pin 30 the ends of which project in such manner as to be slidable in the longer portions of the slots 26. When the pin 30 is in its inward position as shown in Fig. 1, with the ends thereof in the short portions of the slots 26, the bar 28 is held firmly in alinement with the arm 24. Upon slightly lifting the outer end of the bar 28 this bar may be slid outwardly into the position shown in Fig. 5 and then allowed to fold or drop into the position shown in Fig. 6 parallel with the standard 14. This is peizr itted on account of the lower front portion of the arm 24 being cut away, as indicated at 32 in Fig. 4. The angle joining the arms 20 and 24 is provided with an internally-threaded socket 34 adapted to receive the externally-threaded end of an arm or projection 36. A chain 38 is attached at one end to the outer end of the projection 85. The other end of the chain 38 carries a hook 40 adapted to be hooked into an eye 42 carried by socket 163. When this is done the bar 28 will be held in the upwardly-inclined position shown in Fig. 4. The pivotal mounting of the arm 20 permits this movement. The bar 28 and the arm 24 are adapted to support a numher or rods 44 which are in the nature of cross arms. As shown, there are three of these rods. The middle of each rod 44 is formed into a loop 46 and its ends are provided with upwardlyturned hooks 48. The bar 28 is provided with two screws 58, one of which is near the outer end thereof and the other end of which is near the middle. The heads of these screws extend up from the upper surface of the bar. The two outer rods 44 when the device is set up have the loops 46 resting upon the bar 28 just ahead of the screws 50. The rear rod 44 has its loop 46 resting upon the arm 24 near the junction of the latter with the arm 20, which is provided with an upwardly-curved lug 52 behind which the lower portion of the loop 46 fits so as to l00 hold the rear rod 44 in the position shown.

The operation and advantages of my invention will be readily apparent in connection with the foregoing description and the accompanying drawings. The device is adapted for general use when placed in the set-up condition shown in Fig. 1 so that the desired article or articles may be suspended from the several upwardly-turned hooks 48. For example, a tent such as previously referred to may be suspended over the head 110 of a patient. In order to provide proper accommodation to adapt the device to a patient reclining in bed, the tent may be suspended in canted position by placing the device as shown in Fig. 4. In order to do this, the arm 36 is forced downwardly, and upon placing the hook 40 in the eye 42 the supporting bar 28 will be held in the upwardly-inclined position shown. When it is desired to fold the device from the position shown in Fig. 1, the two forward rods 44 are first slid back so as to be carried by arm 24, as shown in Fig. 5. In order to retain these rods in this position, a shoulder 54 is provided on the forward end of the arm 24. Upon now slightly lifting the forward end of the bar 28 this bar may be drawn forwardly to the extent permitted by the pin 30 sliding in the slots 26. The bar 28 will now fold down into the position shown in Fig. 6 and may be kept in place by a clip 56 or other securing means engaging the bar 28 and the socket 16. The projection 36 is unscrewed from the socket 34 and left hanging from the chain 38. It may be kept in place by a clip 58 or other securing means engaging the member 36 and the standard 14.
